Our Mohs Billing Process

What we do
every claim.

Mohs claims require four points of documentation alignment before submission. We verify all four on every single claim — not just when something looks off.

✓
Stage count verificationCross-reference operative note with pathology report to confirm stage count before coding.
✓
Site-specific CPT selectionHead/neck vs trunk/extremity determination drives the 17311/17313 choice — we never guess.
✓
Payer-specific pre-authWe maintain payer-by-payer auth requirements and flag any procedure before it hits the desk uncleared.
✓
Repair code linkageEvery Mohs excision is reviewed for reconstruction CPT eligibility and correctly linked on submission.
✓
Denial root-cause trackingEvery Mohs denial is logged, categorized, and fed back into our coding rules to prevent recurrence.
